Of late, I have been seeing these newly placed "Restriction ends" sign boards on Mumbai--Pune Expressway on certain straight stretches. Can anyone please tell me what does that actually indicate ?

Basically it means that you are not restricted to any of the road signs. So if you've been seeing a speed limit sign of 80 KM/h and then you see the 'Restriction ends' sign it means you are no longer bound to that 80 KM/h speed limit and can speed up till you see another speed limit sign.

During my recent drives on the Mumbai Pune expressway have been seeing the concrete road getting rough at a few spots. The concrete layering has gone literally bad as there has been no re-layering done. I fail to understand why there is no check on the same and is the contractor paid just to collect tolls? recently there was a news that the toll collection would be extended for another 26 years. By that time the E-way will have to be built as new unless some remedial measures aren't taken immediately.

It does not mean you can speed to kingdom come. There is a concept of maximum speed limit for various road types. Unfortunately with traffic being a state subject in India there is no national limitation per say. In 2018, MORTH had prescribed the maximum permissible limit for different categories of road. So the no restriction sign board simply means the previous restriction which was below the prescribed limits are not valid anymore, however the maximum permissible limit - subject to state limitations if any - is still is in play as far as I understand.

For example in BLR city limits, LMV speed limits are 50 km/hr unless specified otherwise to be more or less. On the Bellary Road leading to BLR airport, the limit is 80 km/hr. Only once you leave BLR city limits and pass one of the 'restrictions lifted' signs, can you go upto 100 km/hr unless again local speed limits are in force.

Expected to reduce the distance from 19km to 13km. The tunnel at 24 meters in width will be the widest in the world. A cable stayed bridge will also be added to complete the bypass of twin hill station towns of Lonavala and Khandala.
